` EMERGENCY FUEL finauxy ron AUTOMOBILES.

.. Application filed April 5,

My invention relates to automobiles and has particular .reference` to improvements in l the form, emplacement," arrangement and `operation of auxiliary fuel tanks provided to prevent the stalling ofsuch vehicles during hill-climbing caused by the gasoline level in the supply tank falling below the v level of the carbureter.

The objects ofthe present improvement are to providean auxiliary tank installation thatv willk substantially overcome the` general objections thereto, such `astheir either taking up space where they are in the way, or where they are liable to `be exploded by the heat of the engine; to provide simple and comparatively inexpensive means for connecting the auxiliary tank with the existing arrangements offeed pipes, and to operate the control of flow from both main feed pipe and auxiliary feed pipe by the same means and so that when one of said 'feed pipes is opened to the carbureter the other is y automatically closed.

With the above named objects in view this invention consists in the novel construction, combination and 4arrangement of parts hereinafier described in detail, illustrated in theacconipanying drawing, and more, particularly pointed out in the appended claim.

'in the drawing- Figure 1 is a side elevation of the front section of an automobile tonneau or body7 partly broken away and partly in dotted lines. y.

Figure 2 is an enlarged view of the rear edge of the auxiliary tank and the panel of `the frame which forms .the front end of the right hand side of the car body and to which said auxiliary tank Vis attached.

Figure 3 is an enlarged vertical and longitudinal section of the feed pipe fitting and double "control valve for both main and auxiliary feed pipes.

In the several views 2 represents the front portion of the body of an automobile with the left hand door at the `drivers seat omitted and parts below and in front of said door being broken away to disclose the right existing cars yis substantially `position ofmy a suitable Opening in 1920. serial no. 371,520.

hand side `to which the auxiliary tank is i attached together with its connections.` The auxiliary tank is a thin ,tank 3 about two andgone-half inches in thickness, or with projection into the car beyond the front f. frame of the sideof only about threey fourths of an inch. The auxiliary tankB is .connected with the carbureter ;-4-"-, which'in popular and in large numbersl of as closeto the in Figure 1.` `This connection is Yeffected with the aid having therein a passage 6 which leads from theauxiliary tank to a similar `passage 7 which is made a part of the usual main feed P1P shown by dottedlines in Figure 1 as under the operators seat, but the specific position of which yis immaterial so fares the present invention is concerned. .Through i the fitting 5 extends a vertical andtapered valve bore `10 in which is seated a, valve plu `11 which` intersects the passages 6 and and has a transverse bore or,port 12 therethrough that is rotatable toregister with the passage 6. `In said valve plug is also a simiauxiliary tank `as 'indicated c i of a valve and pipe ttingi e -8- thatleads from the usual tank 9 i lar bore 13 arranged at right angles tothe i bore 12 and similarly rotatable to open or close the passage 7. This ,double valve is operated by means of a rod 14: on lthe lower end of which is a fork 15 that is engaged with a lug 16 on the valve plug 11 and secured to the latter by means of a bolt and nut 17 and 18, a bolt hole being made through the lug and the branches of the fork JFor said bolt, This rod passes through close to the front thereof and has its upper the Hoor of the car f end bent at right angles to form a handle V 19 in front of the operators or chauifeurs position.

The tting 5, shown on an in Figure 3, has three threaded pipe branches 20, 21 and 22 adapted to be ljoined to ordinary pipe unions` the details of which are pipe union, or coupling connection with said branches 20, 21 and 22, ybeing available to carry out the present invention. As shown the passages 6 and 7 unite within the branch 2O and said branch is 'connected by means of any suitable coupling member or union member 23 to the usual pipeI connection or nipple 24 of the carbureter 4. The branch enlarged scale not involved hereinxany acceptable form of 21 is connected by means of a similar couy i pling member 25k with a short pipe 2 6 the upper end ofwhich is connected with a cou pler 28 also connected with an outlet branch 27 in the bottoniofthe auxiliary. tanky), a suitable bore beingmmade through' the ,footboard *29- and floor @it thear for. this purpose. The coupling for the branch 22 is labeledO and connects the main supply pipe Siwith the fitting 5. c

Said tank'j is secured against `lateralinovement on thefoot-board by sev- "eral simple clamps or brackets to the front :side p an`el'of"'the car, which panel is indicatedibythe' numeral` 32. 33 is the dri'vers seatf These brackets are, as shown in 'Figure 21; plain-straps of metalthe respective ends of which are'bent in opposite directions at 4right angles to their'bodies toform vlugs jwhich engagetheside y"ofthe 'tank7 and lugs to'be engagtliby fastening bolts or screws.

Likewise when-the emergency passage fromtlie. tank 3 is .opened the regular passage is automatically'closed to prevent a rearwardlowrfrom the tank 3 toward the tank 9 when traveling up grade. The tank 3 is providedwith the usual cappedv inlet 4:1 and is conveniently accessible, being immediately in front of the car door 41;'

The above described improvementm-ay be installed in and connected with existing cars without anyalterations therein aside from the simple openings through vthe iioor and 'insertion of the fitting 5 in' the regular fuel conduit, all requiring, perhaps, lesstlian an hours work. The space occupiedby the tank 3 does not appreciably' encroach upon edge of the :tanki 3 is lshown with an approximately S curve to make this part of the tank conform to, the similar curvature ,toward the front wall of the side wall in many of existhereon in front of the driver in his seatin lsaid automobile. v In testimony whereofl have hereunto subscribed mv name.
